  abstract = {{S}mall pelagic fish ({SPF}) play extremely important ecological roles in marine ecosystems, form some of the most economically valuable fisheries resources, and play a vital role in global food security. {D}ue to their short generation times and tight coupling to lower trophic levels, populations of {SPF} display large boom-and-bust dynamics that are closely linked to climate variability. {T}o reveal emerging global research trends on {SPF} as opposed to more recently published, ecosystem-specific reviews of {SPF}, we reviewed the literature published in two, 6-year periods in the new millennium (2001-2006, and 2011-2016) straddling the publication of a large, global review of the dynamics of {SPF} in 2009. {W}e explored intrinsic and extrinsic (bottom-up) factors influencing the dynamics of {SPF} such as anchovies, sardines, herrings and sprats within the sub-order {C}lupeidae. {P}ublished research efforts within 16 different biogeographic ocean regions were compiled (more than 900 studies) and compared to identify i) new milestones and advances in our understanding, ii) emerging research trends and iii) remaining gaps in knowledge. {S}tudies were separated into 5 categories (field, laboratory, mesocosms, long-term statistical analyses and spatially-explicit modelling) and discussed in relation to 10 bottom-up categories including 5 abiotic factors (temperature, salinity, p{H}, dissolved oxygen, density), 3 physical processes (advection, turbulence, turbidity) and 2 biotic factors (prey quantity and quality). {T}he peer-reviewed literature reflects changes in the number of studies between the two time periods including increases ({M}editerranean {S}ea, {H}umboldt {C}urrent) and decreases ({A}ustralia, {B}enguela {C}urrent). {O}ur review highlights i) gaps in ecological knowledge on young juveniles and, in general, on the impacts of hypoxia and heatwaves on {SPF}, ii) the utility of paleo studies in exploring population drivers, iii) the continued need to develop spatially-explicit, full life-cycle models, iv) the importance of exploring how density-dependent processes impact vital rates (growth, survival, reproduction), and v) the benefits of international collaboration for knowledge transfer and building unifying hypotheses on the role of bottom-up factors and processes that regulate {SPF} populations.},
